This invention relates to improvements inrolled or forged bars or blanks from which compromise joint bars, vfor connectingand holding the ends of rails of difierent section with their surface and gage in alinement, are adapted to be formed by a squeezing or bulldozing operation, also "to an ,,improved compromise joint bar of the squeezed or bull dozed type produced from the present bar or 10 blank V a For simplicity and economy in production, and because of other resulting'benefits thoroughly appreciated by thoseskilled in the 'rail joint art, it is extremely desirable to manufacturea compromise joint bar by 'a method involving rolling, forging or otherwise suitably forming a bar or blank to fit the high rail of a compromise or step joint combination of rails and. to bulldoze, i. e. squeeze or press a portion of such bar or blank to fit the low'rail of the combination, and .to compe'nsate for the difference in height of the rails; i i

Bulldozing a rolledor forged baror blank to produce a compromise joint bar involves pressing or squeezing a portion of the bar or blankto reduce its height, thus to provide the low fishing section of the bar; also it involves vertically and laterally ofisetting this 3 low fishingsection to compensate for the difference in height and width of the rails and differences in; width of rail heads at gauge point. .pDue, however, to the practical 1 impossibility of taking an ordinary bar of uniform height throughout its length and effecting an abrupt'vertical ofiset between different portions thereof 'by a bulldozing operation, compromise joint bars of the bull- I 'dozed type, as previously produced, have 40 been objectionable chiefly because they did of a] bulldozed compromise rail joint as not afford head fishing contact of the low rail section of the bar extending to the end of the low rail, nor base fishing contact of the high rail section of the bar extending-to the end I of the high rail. To the contrary these consurfaces of the high resulting compromise bar will terminateat their inner orvadjacent ends substantially in the same plane transverselyof the bar, thereby to afford fishing contact and support of the bar at the extreme endsof the rails where ,tion.

tacts, due to the 'curvature'impa rted tothe bar at the junction of the high and low rail sections thereof by drawing of the metal of the bar asa result of thebulldozing opera- .tion,"invariably terminated an objectionable distance spaced from the endsjof the'rails, with consequent failure to provide support for the rails at the very point where good support is extremely to be desired.

' The present invention therefore has 'in View to provide when the bar is subjected to vertical offsetting by a bulldozing operation toprovide a compromise joint b'ar,'the head and base fishing and low sections'of the support is most desirable. With the foregoing general purpose; in view, the invention consists in the features ofnovelty as will be hereinafter more fully described, illustrated in the accompanying drawings and In the drawings wherein like characters of reference denote corresponding parts of the different views: f 1

Figure 2 1s a perspective view of the blank a rolled or forged bar or blank with a distribution of metal Such that defined in the appended claims. i

or bar from which the compromise type of bar. illustrated in Figure 1 is produced.

Figure 3 is an end view of the blank or bar shown in Figure 2; and f Figure 4 is a diagrammatic side elevation heretofore produced, illustrating the lack of contact between the bar and the rails which n is eliminated by means of the present inven- In carrying out the present invention a bar or blank A of any desired cross section, capable of being bulldozed to produce a compromise joint bar, is rolled, forged or otherwise formed of a height to approximately fit the high rail of the particular step joint combination of rails with which the bar is intended ultimately to be used.

In accordance with common practice a portion of the bar A is adapted to be squeezed or pressed, i. e., bulldozed, to reduce the height thereof to produce the low fishing bar section 10 to fit the low rail of the particu lar step oint combination of rails with which the bar is intended for use, and in order to compensate for the difference in the height of the rail the bulldozing operation includes offsetting of the low fishing section 10 of the bar with respect to the high fishing section 12 thereof.

Heretofore, due to the bar or blank A bein of uniform height throughout its length, setting of the low fishing section with respect to the high fishing section 12 thereof has resulted in the intermediate portion of the head 14 and the base 16 of the bar, at the junction of the high and low fishing sections thereof, taking the form of a gentle curve extending a considerable distance longitudinally of the bar with the result, as shown in Figure 4 of the drawings, that the base fishing contact of the high fishing section 12 of the bar terminated an excessive distance from the end of the high rail and the head fishing contact of the bar with the low rail terminated an excessive distance from the end of the low rail. This lack of contact obviously may be reversed with relation to the high and low rails in cases where the depth of the head of the low rail is greater than'the depth of the head of the high rail.

To compensate for the draw of the metal of the bar incident to Vertically ofisetting the low fishing section 10 thereof the present invention contemplates an addition of metal to the head 14 and the base 16 of the bar inter- -mediate the ends thereof so that when the bulldozing operation is performed a substantially abrupt shoulder will be produced at the junction of the head and base portions of the high and low rail sections of the bar. These additions of metal designated 18 and 20, re-

spectively, are built up upon the fishing surfaces of the head and base of the bar so that,

primarily, it is these fishing surfaces that are affected, the metal of the additions or protuberances 18 and 20 being so distributed of greater cross section intermediately and tapering towards the ends of the bar, gradually merging into the latter, for example that the abruptness of the shoulder formed at the junction of the high and low fishing sections 10 and 12 is so pronounced that the head and base fishing surfaces of the high and low fishing sections 10 and 12 terminate substantially in the same plane transversely of the bar. This means of course that when the bar is incorporated in a joint as illustrated in Figure 1 both the head and the base fishing contacts of the bar with the rail will extend entirely to the end of the rail thereby providing complete and efficient support for the latter.

A bar produced in accordance with the present invention may or may not be provided with a central reinforcement on the outer face of the web thereof, as desired. A central reinforcement such as is disclosed in Armstrong Patent 1,663,619 may, for eX- ample, be conveniently formed on the bar.

Without further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will of course be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention and scope of the appended claims.

I claim:

1. A blank from which a compromise joint bar is adapted to be bulldozed provided with a fishing surface having medial enlargement of metal within planes defining the inner and outer limits of said surface to compensate for draw of the metal of the blank incident to vertically offsetting the blank to compensate for the difference in the height of the rails.

2. A blank from which a comprise joint bar is adapted to be bulldozed comprising a head, a web and a base, and a body of metal protruding upwardly from "the head of the blank at the proposed point of junction of the high and low fishing sections of the finished bar, distributed to compensate for draw of the metal incident to vertically 0E- setting the blank to compensate for the difference in the height of the rails. i

3. A blank from which a compromise joint bar is adapted to be bulldozed comprising a head, a web, and a base, and a body of metal protruding downwardly from the base of the bar at the proposed point of junction of the high and low fishing sections of the finished bar, distributed to compensate for draw of i the metal of the blank incident to vertically offsetting the blank to compensate for the difference in the height of the rails. V

4. A blank from which a compromise joint 7 vertically offsetting the blank to compensate for the difference in the height of the rails.

5. A blank from which a compromise joint vbar is adapted to be bulldozed inclusive of a fishing surface provided intermediate its ends and within its inner and outer limits with a body of metal of greatest thickness intermediate its ends and merging into said bar to compensate for the draw of themetal of the blank incident to offsetting the blank to compensate for the difference inthe height of the rails.

In testimony whereof I hereunto aflix my signature.
